Caenorhabditis elegans, a tiny roundworm, spends much of its lifetime searching for soil bacteria to eat. This humble creature possesses 302 neurons, which may not seem like a lot compared to the billions of nerve cells that ...
A new study of an otherworldly creature from half a billion years ago - a worm-like animal with legs, spikes and a head difficult to distinguish from its tail - has definitively identified its head for the first time, and ...
The complexity of biology can befuddle even the most sophisticated light microscopes. Biological samples bend light in unpredictable ways, returning difficult-to-interpret information to the microscope and distorting the ...
Archaeologists from the University of Basel discovered eggs of intestinal parasites in samples from the former Celtic settlement 'Basel-Gasfabrik,' and concluded that its population lived in poor sanitary conditions. Using ...
Choosing between two good things can be tough. When animals must decide between feeding and mating, it can get even trickier. In a discovery that might ring true even for some humans, researchers have shown that male brains ...
A growing body of evidence suggests that environmental stresses can cause changes in gene expression that are transmitted from parents to their offspring, making "epigenetics" a hot topic. Epigenetic modifications do not ...
(Phys.org) —Researchers have shown how to use a new imaging platform to map lipid metabolism in living cells, discovering specifically where cholesterol is stored and pointing toward further studies in obesity, diabetes ...
The complexity of biology can befuddle even the most sophisticated light microscopes. Biological samples bend light in unpredictable ways, returning difficult-to-interpret information to the microscope and distorting the ...
As multicellular creatures go, planaria worms are hardly glamorous. To say they appear rudimentary is more like it. These tiny aquatic flatworms that troll ponds and standing water resemble brown tubes equipped with just ...
Some three billion base pairs make up the human genome—the floor plan of life. In 2003, the Human Genome Project announced the successful decryption of this code, a tour de force that continues to supply a stream of insights ...
